Hello
I have read that under Solaris one can use DTrace to get I/O request size distribution on a global scale (also on a per process/pid basis). See for example

Can anyone recommend an alternative to get similar information under CentOS? I looked into dtrace for linux but it seems still work in progress, even putting aside CDDL issues ...
